TurboGL w/G400

[HoangN@work]

Sorry to post this question if it has already been answered. I've been doing some serious tweaking with my system and can't seem to get any more juice from the TurboGL drivers as opposed to the standards drivers in Q3. I'm running an athlon 500 @750 with vanilla g400 at 150/200. Has anyone else had this problem? I did try to copy over the k7 driver and rename it just in case it was using the wrong driver. Same thing.
